Application filed October 13, 1927. Seriallfo. 225,891.

My invention relates to a new and useful improvement in a coffee percolator, in which the coffee grounds are positioned below a container and the heated water placed above in the container and permitted to percolate or leach through the coffee grounds into a desired position below.

It is an object of the present invention to provide a coffee percolator of this class which will be simple in structure, economical of manufacture and highly eflicient in use.

Another object of the invent-ion is the provision of a coffee containingeompartment in which the coffee grounds may be compressed as desired, so as to retard tothe desired degree the seepage or leaching of the liquid therethrough.

It is another object of the invention to provide a device of this class which may be easily and quickly assembled and easily and quickly cleaned. 7

Another object of the invention is the provision in the compressing member of a chamscribed an her positioned above into which the coffee grounds may enter as they swell during. the

eaehin of the liquid therethrough.

Anot er object of the invention is the provision of a percolator in which the juices of the. colfee may be extracted without removal of the tannic acid therefrom.

Other objects will appear hereinafter.

The invention consists in the combination and arran ement of parts hereinafter declaimed. Y

The invention will be best understood by a reference to the accompanying drawin which form a part ofthis specification and 1n which,

Fig. 1 is a central vertical sectional view of the invention. v

Fig. 2 is a sectional view taken on line 22 of Fig. 1.

Fig. 8 is a sectional view taken on line 3-3 of Flg'. 1. I

In the drawings '1 have illustrated the invention adapted for .use. with a lower con.-

tainer 7 having the pourin spout 8 and a handle 9mounted thereon,

e upper end 10 bemg open and provided with an upwardly projecting neck forming flange 11. An upper container 12 is itioned'above' the con tainer 7 ,having its ase flared as at 18 to provide shoulders which engage the upper edge of the flange or neck 11. A neck 14 extends outwardly from the flared base 13 and is interiorly and 'exteriorly threaded. A disc 16 in which perforations 17 are formed is placed in engagement with the lower edge of the neck 14 and the inwardly directed flange 23 which is formed on the neck. Engaging the undersurface of the disc 16 is a filter 21 which is formed from a layer of fabric or other suit able filtering material. A disc 25 is arranged to engage the undersurface of the filter 21, this disc 25 being provided with perforations 26. The inwardly directed flange 23 on the ring 15 serves to clamp the, two discs and the filter in assembled position on the lower end of the neck 14. The rin 15 is threaded on the neck 14 and provide with the inwardly directed flange 23 which serves to bear a ainst the undersurface of the disc 25 in the 0 amping operation. V

vWhen the coffee grounds of the desired amount have been placed in the neck 14,.the disc 18, which serves as a cover and which is provided with perforationslQ and thehandle 20, may be threaded downwardly so asto compress the grounds against the disc 16, the degree of compressing of the grounds regulating the rapidity of the seepage or leachlng of the liquid therethrough, which is placed in the container 12. As shown in Fig. 1, the disc 18 is formed concave at its center 24 to provide a space into tainer 7, upon which the coffee is ready for use.

Cofiee made in this manner is proven to be most palatable, free from injurious ingredient's and particularly free from tannic acid. Furthermore, there is, from the cheaper grades of coffee, produced a cofiee which is possessedof a most desirable flavor.

While I have illustrated and described the preferred form of my invention, I do not wish to limit myselfto the precise details of such variations and modifications as come within the scope of the a pended claim.

Having thus describe my invention what I claim as new and desire to secure by Letters Patent is A coffee per colator of the class described, comprising: a lower container having its up per end open and provided with an upwardly directed flange around said opening; an up per container; an inwardly flared base on sald container, inwardly of the marginal edges thereof, to provide a shoulder for engaging the upper edge of said flange; an interiorly and exteriorly threaded neck depending centrally from said base and extending into said lower container; an inwardly directed flange on the lower end of said neck; a ring threadable on the exterior of said neck; an inwardly directed flan e on the lower end of said ring; a filter mem r engaging the lower end of said neck; a erforated disc engaging the undersurface 0 said filter, the inwardly directed flange on said ring retaining said perforated disc and said filter in engagement with the lower end of said neck; and a perforated disc threadable into said neck for compressing coffee therein a ainst said filter and disc, said threadable per or'ated disc having a concave center.

In testimony whereof I have signed the foregoing specification. HENRY C. BIETTE.
